There is provided an image recording apparatus including a carriage, a head, a velocity sensor, and a controller. The controller obtains velocity data of the carriage from the velocity sensor, determines a threshold value based on the velocity data, records an image on a recording medium, and suspends a recording pass when the controller has determined that a velocity indicated by the velocity data is lower than a velocity corresponding to the threshold value. The controller can execute a first recording mode and a second recording mode in which the velocity of the carriage is faster than that of the first recording mode. The velocity data for the first recording mode is obtained in a warm-up time after a recording command is received until recording of the image is started. The velocity data for the second recording mode is obtained in other time other than the warm-up time.
